Em W. MISSED, 0! WEST W'EBSTERiNEW YORK comm PLUG I Q Application filedMay 28, 1930. Serial No. 456,434.

The object of this invention is to provide a new and improved form ofsafety outlet plugs.

Another object of the invention is to make u the plug so that the wiresleading out therelrom are more efl'ectively separated and cannot comeinto contact with each other so as to cause a short circuit.

.lnother object of the invention is to pro- .to ride for the easyassembling of the plu Another object is to provide an un ercut suriaceon the plug which serves as a handle by which the plug is more easilypulled out irom the socket thus avoiding any strain on lit the wiresthat would tend to lrom the connections.

These and other objects of the invention will be illustrated in thedrawings, described in the specification and pointed out in the fillclaim at the end thereof. ln the drawings: Figure l is a side elevationof the plug assembly.

lligure 2 is a section through the complete all plug on the line 200 229of Figure 4.

llioure 3 is aside elevation of the male member at the plug.

Figure l m a top plan View Oll the member shown in Fig. 3. V

Figure 5 is a top plan view at a modified term of the member shown inFigure 4.

la the drawings like reference numerals indicate lilre parts.

lln the drawings relf'erence numeral 1 indicates the cap or ternalemember of the plug. 2 indicates the male member oi the plug. The malemember has a body that is exposed outside of the plug when assembledwhich body has the shape of a truncated cone. At the top the male memberis cone shape, and this cone shaped top is cut away to term the listdecks l8 and hi which separated by the cone shape member which serves asa pa tion between the desire l3 and i i and l orms pocket on either sideof the Tlhro 'h the body at the male member eaten he contact members 3and ll which members are brass and extend through and project beyond thebase so that they t all) pull them loose can be inserted in the outletsocket. These contact members are fastened to the decks 13 and '14 bythe screws 5 and 6. These screws are also adapted to fasten to thecontact members the wires 7 and 8 of the lead in cable or lamp cord 9.The base is provided With a male thread 10 and a female member isprovided with a female thread 11 which engages with the male thread 10of the base.

The cap 1 is made large enough so as to enclose a chamber with amplespace between it and the top of the male member of the plug where thecontacts are located. As shown in Figure 4, the top of the male memberis out out on either side of the cone or partition 12 as though by areamer to form the decks 13 and 14., and as shown in Fi ure 5 the coneis cut with parallel valves as t ough by a saw or by a mill to form thesemicircular decks 13A and 14A. In either case the mutilated cone shapemember 12 forms a partition between the pockets formed on either side ofit, and prevents the wires on either side from getting crossed andmaking contact with the wires on the other side.

The cone shape surface of the ex osed part of the base together with thecap 1 arms an undercut surface which can be grasped eflectively by thelingers in pulling the plug out of the socket. With plugs now in use theoperator will ordinarily not take hold oi the plug itself, but will takehold of the wires in pulling the plug out of the socket. This puts astrain on the wires with the possibility always of pulling the wiresloose from one or more of the binding screws and thus causing a shortcircuit. By making the plugin the manner shown the body of the plugadords a convenient handle that reduces or completely removes thispossibility of pulling the wires loose.

lit will also be understood that the male female members will be made ofbakclite or some other form of insulating material that is easily moldedjust as commercial plugs are now made.

ll claim:

lln an outlet plug, the combination oil a male member, a cap threadedthereon a ooni cal partition eutendingcentrally across the till till

tilt

top of the male member inside of the cap, an arcuate portion being cutout on either side of the partition forming a deck, a contact memberextending from each of said decks out through the body of the male mem--her, a hole in the topof the cap through WhlCh lead wires are adapted toextend to the contact members on either side of said partition, saidcdntact members each having an end turned down over its deck, said endshavin openin s therein, said decks having threa ed openings therein,screws passing through the openings in the contact members and engagingwith the threaded openings in the deckand adapted to clamp the contactmembers to the body portion, and

adapted to clamp the lead wires against the contact members.
